[sdiy] Any noise avantage to parallel 2164 VCAs?

[Tom Wiltshire]

Hi all,

A quick query, if I may: Is there any noise advantage to using two 2164 VCAs in parallel?

I’ve got a circuit that uses two VCAs, so there are two others spare on the chip. And then it occurred to me that there might be a minor gain by using them in parallel pairs. It’s a case of “well, they’re there so we might as well use them” if there’s no reason not to.
 Or would it be better to simply disable the unused sections?

Thanks,
Tom
